Innovation Version

      Key Features

      • StratoVirt: Combines high security and performance with lightweight loads, low power consumption, and flexible component splitting for trusted virtualization platform in all scenarios.

        • Uses the Rust language, supports seccomp and multi-tenant isolation, providing a secure and trusted operating environment.
        • Supports startup within 50 ms and memory noise floor of less than 4 MB, achieving the ultimate performance and lightweight deployment in various scenarios across-device-edge-cloud.
        • Supports multiple hardware acceleration virtualized engines, such as x86 VT and Kunpeng-V.
        • Supports device scaling within milliseconds, providing flexible resource scaling capabilities for lightweight loads.
        • Scalable device models, supports complex device specifications such as PCI, and compatible with the QEMU software ecosystem.
        • Supports multiple computing, network, and storage acceleration solutions, and flexible collaboration of heterogeneous computing power.
      • iSula: A lightweight container solution that unifies IoT, edge, and cloud computing.

        • Optimized operation performance for the startup and container lifecycle.
        • isula-build, a container image build tool that provides secure and fast container image build capabilities.
        • Secure and trusted VM startup for enhanced VM security.
      • Enhanced virtualization features

        • Optimizes VM lock preemption with dual-layer scheduling and Hypervisor-aware VM scheduling, delivering higher performance in the multi-core overcommitment scenario.
        • Optimizes the IPI interruption performance using the Guest-Idle-Haltpoll mechanism, improving the database service performance.
        • For the virtualization feature of the ARM platform, supports the CPU/memory hot plug and the custom mode for the KVM CPU, making resource configuration more flexible.
        • Quickly collects performance indicators of a VM using the O&M tool VMTOP.
        • Enables hardlockup detection using the PMU NMI watchdog feature.
      • Kernel feature enhancement

        • Enhancement for IMA commercial use: Based on the open source IMA solution, improves security, performance, and usability to facilitate commercial use.
        • NUMA Aware Qspinlock: Improves system performance by reducing cross-NUMA cache synchronization and ping-pong operations caused by lock competition.
        • Ktask parallelism: A kernel task parallelism framework that supports the parallel operation of kernel tasks.
        • MPAM resource control: Supports Cache QoS and memory bandwidth control technology for the ARM64 architecture.
        • Memory system lock optimization: Optimizes vmalloc allocation lock and Pagecache lock.
      • Programming languages and compilers

        • JDK8 enhancement: Supports the APPCDS feature and crc32 hardware acceleration instruction.
        • GCC optimization: Supports cyclic optimization, automatic vectorization, and global optimization.
      • Hardware and chip enablement

        • Raspberry Pi: Supports the Raspberry series boards.
      • Desktop support

        • UKUI: Default desktop environment of the Kylin OS. Its layout, style, and usage habits are similar to those of the traditional Windows OS.
      • Intelligent O&M

        • A-Tune: An intelligent system performance optimization engine that infers service features and configures the optimal system parameter set for the optimal service operations.
